Hubby finally installed my new mirror on my bike today, and then we went for an 11-mile ride. (My first 11-miler; I'm progressing!) The mirror is the kind that installs on the handlebars and sits above them on its own 'stilt.' I've never used a mirror on a bike before, so was curious as to how it would be.
It took me a few minutes to get it adjusted right, but once I did, I loved having it! I could tell when Dear Hubby had had enough of 'drafting behind me' (right....) and was coming around to pass without warning me -- so I could pretend to 'smoke him,' lol. More importantly, I could see cars coming up behind me and make sure I moved far enough to the right. The most important thing I noticed was that not only did I see the car behind me coming (that I could hear coming, anyway), but I could also see the car BEHIND that one, which I would not have heard over the first one's motor. I found it almost invaluable!
At first I was disappointed because whenever I hit a bump, the mirror would move and not be in my line of vision again. But after that happened several times, Hubby figured out that he hadn't tightened the screw enough that makes it adjustable/keeps it from moving, and once that was accomplished it was great.
So for now, I've got it on, and I like it, I like it!
